External USB hardrive

SATA hardrive external enclosure, with AC power supply, with usb and sata connectors
i formatted and partitioned it without problem using the SATA connection

yet using the USB connection theres issues:

When its connected the safely remove icon appears
In device manager it is recognized as
a USB device - under drives
USB mass storage device - under USB serial controllers
Its not recognized in disk management nor in my computer

I know its not got a conflicting mapped network drive letter, as its assigned X:

Exactly the same issue on two seperate computers on all the usb slots i had the will to try. USB pen drives work fine.

I've read every thread i could find and most problems seem to be the conflicting drive letters, i was wondering if it might need some changes to the BIOS?

This might sound silly, but make sure your SATA drive is plugged into the enclosure well.. Meaning double check the power and data cables. It sounds like Windows is recognizing the SATA to USB chipset (enclosure), but not the drive itself (Which should show up in device manager under hard drives).
